I am starting to impliment enterprise PDM at our place. I usually have administration and windows explorer open to preview the data cards i am working on. The first time it happened i noticed my processor was sitting at 70%. I opened task manager and saw 4 or 5 instances of eDrawingOfficeAutomator.exe running, each using >= 100 MB of memory and 13% of the CPU. I asked my VAR about it and they said it was from the preview tab in windows explorer. So I disabled the preview but now I get mulitple insances of EModelViewer.exe running that don't seem to close unless i stop the process in task manager.
